PATENT OFFICE GUIDE AND DEFLECTOB FOR. amss CHARGES '2 Claims. (01. 49-14) The invention relates to means for guiding glass charges from a'feeder to the molds of a forming machine, and deflecting the charges from the molds when the machine is shut down.

One of the objects of the invention is to provide a device of this character which is extremely simple in construction, and quickly and easily shiftable between feeding and deflecting position, and yet which operates in a highly emcient manner to perform the operations of guiding the charges to the molds or deflecting the charges from the molds.

Another object of the invention is to provide a simple construction, automatically operated, for cooling the deflector when it is thrown into use. i w

While the invention is particularly intended for use with feeders located a considerable distance above the forming machine, such as illustrated in the patent to F. C. Flint, No. 1,764,832, granted June 1'7, 193 yet it is equally well adapted to use with feeders located at a conventional distance above-a forming machine. Also, of course, the invention is not limited to use with any particular type of feeder, or with any particular type of forming machine.

Various other objects and advantages of the invention will be apparent to those skilled in the art, from the following detailed description, when taken in connection with the accompanying drawing, in'which,

Figure 1 is a side view of the apparatus-with the guide in position to dellvercharges to the molds.

- Figure 2 is a top plan view thereof.

Figure 3 is a front view of the apparatus, with the parts shifted to deflect the charges from the molds; and

Figure 4 is a sectional view of the deflector, taken on line 4-4 of Figure 3.

Referring to the drawing in more detail, numeral l.indicates a pipe which leads vertically downward from a glass feeder (not shown) to a point over a rotatable mold table 2 carrying any desired number of molds 3. The main purpose of this pipe, as described in the above-mentioned depending from this slide are a vertical guidetube 5 and an inclined deflector tube 6; the tubes being aligned with openings I and 8 respectively, in

the slide 4.

Numeral 9 refers to a housing in which'th slide is mounted; and in the specific embodiment illustrated the slide is removably retained in the housing by retainer members It. The housing is provided with a collar Ii, which is removably attached to the pipe I, by means of set screws [2. 5 If the guide and deflecting apparatus is to be used in connectionwith a feeder located at a conventionaldistance above the mold table, the pipe I is omitted, and the housing can be carried by any suitable bracket.

With the parts as shown in Figures 1 and 2, the glass charges will fall vertically from the feeder and drop into the molds as they are successively brought into position beneath the guide tube 5, and this guide tube will center the charges in the molds. If desired, an auxiliary guide such as described in my application Ser. No. 115,008,

flied December 9, 1936, may be removably mounted on the lower end of the guide tube.

When the forming machine is to be shut down, and the feeding .of the glass charges continued so that there will be no material change in the, temperature or condition of the glass, the charges must be deflected from the molds. In order to deflect the charges, the slide 4 is shifted to bring 25 the opening 8 and the deflector G into alignment with the pipe i.

For the purpose of shifting the slide between feeding and deflecting positions, an operating lever 13 is pivotally mounted on a bracket l4 at- 30 tached to the housing 9. The lower end of this lever is provided with a slot I 6 which receives a pin l6 attached to the slide 4. Thus by shifting .the lever IS the slide is moved in either direction will be properly aligned with the pipe I, stops ll are provided on each end of the, slide 4.

When the deflecting tube is in operative position .the glass charges slide down the deflector and are delivered to any suitable receptacle. If the deflector were not cooled the-charges would quickly overheat it, with the result that the charges would adhere to the deflector. To prevent this ther deflector tube is provided with a jacket 48 on its bottom and sides, to receive a cooling fluid such as water or air. For admitting cooling fluid to the jacket a nipple I9 is provided adjacent its upper end, and a. similar nipple 20 is provided adjacent the lower end of the jacket for discharging the fluid. If cooling water is used a hose 2| or the like is attached to the nipple In to carrythewastewatertoadrain.

When the deflector tube 6 is in inoperative position, of course it is unnecessary to employ cooling water or air, and to save the expense of supplying the cooling medium when not needed, and

also to make certain that the cooling medium will be admitted to the jacket immediately upon the movement oi the deflector to operative position, I have provided means for automatically admitting cooling medium to the deflector when it is movedto operative position, and for automatically shutting off the cooling medium when the deflector is moved to inoperative position. Numeral 22 refers to a valve attached to the nipple i9, and receiving water or air from a hose or flexible pipe 23 communicating with a source of water or air.

The valve stem, indicated 'by numeral 24, is

squared, and is received in a slot 25 provided in the lower end of an arm 26. This arm is pivotally mounted on a pin 21 carried by the stationary housing 9. Thus when the deflector is moved to operative position to receive and deflect the glass charges, the valve stem 24 will be turned to open position to admit water or air to the jacket ll, and when the deflector is returned to its inoperative position the valve stem will be turned in the opposite direction to shut of! the position, thereby avoiding overheating of the deflector due to the failure of the operator to open a manually operated valve, and also reducing the operating cost oi the device by employing the cooling medium only when the deflector is in its operative position.

Various changes and modifications may be made in the speciflc embodiment of the invention disclosed herein, without departing from the spirit of the invention, and all such changes and modifications are intended to be included within the scope of the appended claims.

What I claim is:

1. Apparatus for delivering glass charges to molds, including a housing, a slide mounted in the housing, a vertical guide member and an inclined deflector member depending from said slide, the slide being reciprocable to bring either the guide member or the deflector member into position to receive glass charges, a cooling jacket provided on the deflector, and means operated by the reciprocable movement of the slide to control admission of cooling medium to the jacket.

2. Apparatus for delivering glass charges to' molds, including a housing, a slide mounted in the housing, a vertical guide member and an inclined deflector member depending from said
